Can't define scene in multiple packages?

[AnderssonPeter]

Home Assistant release (hass --version):
0.40.0

Python release (python3 --version):
3.6.0

Component/platform:
Packages

Description of problem:
I tried to model my configuration using one package per room, this way its easy to navigate the files.
But it seems im not allowed to add the scene component to multiple packages?

Expected:

Problem-relevant configuration.yaml entries and steps to reproduce:
The following works:

homeassistant:
  packages:
    room1:
      input_boolean:
        room1_test:
          name: test1
          initial: off
    room2:
      input_boolean:
        room2_test:
          name: test2
          initial: off

But the following does not:

homeassistant:
  packages:
    room1:
      input_boolean:
        room1_test:
          name: test1
          initial: off
      scene:
        - name: test1_on
          entities:
            input_boolean.test1: on
    room2:
      input_boolean:
        room2_test:
          name: test2
          initial: off
      scene:
        - name: test2_on
          entities:
            input_boolean.test2: on

What makes scene so different i as switch, automation, group and input_boolean all work great.

[31m17-03-15 17:44:08 ERROR (MainThread) [homeassistant.config] Package room2 setup failed. Component scene may occur only once and it already exist in your main config (See C:\Users\...\AppData\Roaming\.homeassistant\configuration.yaml:23).

I'm also trying to split my config into 'per room or area' and hit the same problem.
It'd be nice to get 'customize' working in packages as well.

@christianwaite
customize is working as intended for me!
i have the following package.yaml file for each room and it contains

homeassistant:
  customize: !include customize.yaml

then customize.yaml has this content:

switch.outside_light1:
  icon: mdi:tree
  friendly_name: Träd
switch.outside_light2:
  icon: mdi:led-off
  friendly_name: Terrass

but as scene's don't work i just wrote some scripts instead and they seem to do the job so far even if its alot more yaml code needed..

[christianwaite]

Ahh yes! I was missing the 'homeassistant:' bit before 'customize'.
Thanks!

As this is now closed does that mean it will be included in the next release? It would be nice to use scenes instead of verbose scripts.
